report is open

Discussion Lock: Any
Operating System: GNU/Linux

Details:
Opening the cities report (F4), sorting by "Currently Building" and then
buying something causes a segfault.
The problem seems to be that the client stores NULL entries in the gtk tree
in merge_list_stores(). This causes the compare function to be called with a
NULL string which segfaults when it tries to split it.
As a workaround I patched
int cityrepfield_compare(const char *str1, const char *str2)
to handle NULL strings. This avoids the segfault but then GTK complains
about
(freeciv-gtk2:6001): Gtk-CRITICAL **: gtk_list_store_move_after: assertion
`!GTK_LIST_STORE_IS_SORTED (store)' failed
and the list of cities shown in the report becomes incomplete. Closing and
reopening the report fixes that.
Patch attached.

Prevent segfault when buying things. Does not fix the real problem.
